Definitions

  • the invention relates to a method for operating a heater, preferably with ⁇ lzerstäuberbrenner.
  • Oil atomizing burners are often designed as a so-called "one-shaft machine” in which the combustion air blower and the oil pump are driven by a single motor via a shaft.
  • the oil pumps are usually designed as gear pumps. Throttling to the partial load modulation via throttle valves in the air or oil path.
  • a method for operating a heater in which a measured speed signal of a fan is compared with a reference signal.
  • the reference signal takes into account the transient process during a load change. If the deviation between the measuring signal and the reference signal is smaller than a predetermined value, then the load change corresponds to the expected course.
  • the amount of fuel gas is regulated in accordance with the present combustion conditions, in particular the signal of a separate ionization electrode.
  • Object of the present invention is to allow a low-pollution combustion and safe operating conditions during a load change.
  • a frequency or a step number is detected as the actual value.
  • the setpoint is not abruptly but continuously changed in a change in the power setting, so that the sluggish actuators with their actual value can better follow the setpoint.
  • FIG. 1 shows a burner 10, which is connected to a fan 2 in an air line 8.
  • the blower 2 has a motor 4, which is connected to a control 1.
  • a speed detection 6 is coupled, which is also connected to the controller 1.
  • An oil line 9 protrudes into the air line 8 upstream of the burner 10.
  • an oil pump 3 by a motor. 5 is driven.
  • the motor 5 is connected to a frequency detection 7.
  • the speed detection 7 and the motor 5 are connected to the control.
  • FIG. 2 shows speed lines n during the change of a power specification.
  • the burner 10 is initially operated with a specific power setting, so that the fan to a certain speed n G, should and the reciprocating pump 3 with a certain stroke frequency f P, is operated.
  • the power setting is changed, increased by 50% in the present example.
  • the control unit 1 now attempts both the setpoint fan speed n G, should , and the setpoint stroke frequency f P, soll . to reach as soon as possible. Due to the inertia of the blower 2 and the reciprocating pump 3, however, the target speed n G, should as well as the Sollhubfrequenz fp , should . only with time delay.
  • the speed n G is the blower 2 increases continuously until it reaches the target speed n G, should at a time t 3 . Since the reciprocating pump 3 acts nimble their stroke frequency f P 1 rises faster and already reached at a time t 2, the Sollhubfrequenz f P should.
  • the entire new quantity of fuel oil is available at the time t 2 , but only a reduced amount of air. As a result, the combustion becomes richer and there is an increase in nitric oxide and carbon monoxide formation.
  • the blower 2 is given a new nominal speed n G, soll .
  • the fan 2 follows due to its inertia, however, the speed line n G, is .
  • K is a constant representing the ratio between the actual signal for the blower 2 and the setpoint signal for the pump 3. Since the reciprocating pump 3 is very fast, it follows the current state value of the blower 2 almost proportionally.
  • the target signal n G is not abruptly, but continuously increased.
  • the inertial blower 2 that the deviation between the actual signal and the desired signal is relatively small and can be neglected given a corresponding gradient.
  • the reciprocating pump 3 with its actual signal which is measured with the frequency detection 7, the target signal for the blower 2 pretend.
  • controllable gas valve instead of an oil pump.
  • This gas valve can preferably be controlled by a stepping motor, so that the number of steps of the stepping motor is detected here.
